A UDP interface can be useful for communicating over IP networks, both private and the internet. It can also allow broadcast communication over IP networks, so it can provide an easy way to enable connectivity with all other peers on a local area network.

Please Note! Using broadcast UDP traffic has performance implications, especially on WiFi. If your goal is simply to enable easy communication with all peers in your local ethernet broadcast domain, the Auto Interface performs better, and is even easier to use.

The below example is enabled by default on new Reticulum installations, as it provides an easy way to get started and to test Reticulum on a pre-existing LAN.

[[UDP Interface]]

type = UDPInterface

interface_enabled = True

listen_ip = 0.0.0.0

listen_port = 4242

forward_ip = 255.255.255.255

forward_port = 4242

# The above configuration will allow communication

# within the local broadcast domains of all local

# IP interfaces.

# Instead of specifying listen_ip, listen_port,

# forward_ip and forward_port, you can also bind

# to a specific network device like below.

# device = eth0

# port = 4242

# Assuming the eth0 device has the address

# 10.55.0.72/24, the above configuration would

# be equivalent to the following manual setup.

# Note that we are both listening and forwarding to

# the broadcast address of the network segments.

# listen_ip = 10.55.0.255

# listen_port = 4242

# forward_ip = 10.55.0.255

# forward_port = 4242

# You can of course also communicate only with

# a single IP address

# listen_ip = 10.55.0.15

# listen_port = 4242

# forward_ip = 10.55.0.16

# forward_port = 4242
